At our shop in Green Lanes N4 1DX, next to Homebase, we replace Chubb Detainer Lock sets.

NORTH LONDON LOCKSMITHS Ltd. have been based in North London for 35 years and have been selling Chubb Locks since establishing our company at that address.

Instead of selling you a new Chubb Lock, we can change the detainers inside your lock, giving you new keys, hence new security and SAVING YOU MANY POUNDS.

For instance to replace a Chubb Detainer Lock 3G110 would cost you a large amount of money, to replace the 5 detainer pack, at our shop next door to Hombase in Green Lanes, North London, it would cost you a third of the cost, including 2 new keys.

Even better, if you were to purchase the detainers with 2 new keys from us and fit them yourself, it would be even cheaper, we would supply easy to fit instructions, and will send to anywhere in the United Kingdom.


We can also replace locks with many of the same keys, for example you may have a Chubb 3G110 lock on the front door of your Home or Business and a Chubb 3R35 lock on the back door, these can be done on the same key, rather than buying new locks, SAVING YOU IN THE REGION OF NEAR TO £150.00 PLUS.

As well as this they can also be made up on a Master suite.

We can make up as many keys as you like, remembering that the detainer packs come with 2 keys.

The more locks you have in you Home or Business, the more money saved.
As well as the Chubb Detainer Lock replacement we can also change the lever pack on Chubb 3G114 this can save money, but the bonus is that the Chubb sash lock can be passed with the Chubb 3K74 Lock. This means that you can pass your back and side doors with your front door, in fact 1 key will cover the whole sash and deadlocks in your Home.
